ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for all Airbus SAS Model A330–200 Freighter series airplanes, Model A330–200 and –300 series airplanes, and Model A340– 200 and –300 series airplanes. This proposed AD was prompted by defects found during production tests of ram air turbine (RAT) units; investigation revealed that the defects were due to certain RAT hydraulic pumps having an alternative manufacturing process of the pump pistons. This proposed AD would require replacing any defective RAT hydraulic pump with a serviceable part and re-identifying the RAT module part number. We are proposing this AD to address the unsafe condition on these products. SUMMARY: We must receive comments on this proposed AD by October 15, 2018.

Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2018–0062, dated March 20, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus SAS Model A330–200 Freighter series airplanes, Model A330– 200 and –300 series airplanes, and PO 00000 Frm 00011 Fmt 4702 Sfmt 4702 Model A340–200 and –300 series airplanes. The MCAI states: Four A330 RAT units were returned to the supplier due to low discharge pressure. These defects were detected during Airbus production tests. Subsequent investigations by the RAT manufacturer UTAS (formerly Hamilton Sundstrand) revealed that some RAT hydraulic pumps, [part number] P/N 5916430, were involved in an alternative manufacturing process of the pump pistons. This resulted in form deviations (rough surface finish and sharp edges), which caused excessive wear and damage to the bore where the pistons moved. This condition, if not corrected, could lead to low performance of the pump, possibly resulting in reduced control of the aeroplane, particularly if occurring following a total engine flame out, or during a total loss of normal electrical power generation. To address this potential unsafe condition, Airbus published [service bulletin] SB A330– 29–3130 and SB A340–29–4098, providing instructions for identification and replacement of the affected parts. For the reasons described above, this [EASA] AD requires replacement of the affected parts. This [EASA] AD also requires re-identification of the RAT module. You may examine the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2018– 0764. Other Related Rulemaking The FAA issued AD 2016–14–01, Amendment 39–18582 (81 FR 44983, July 12, 2016); corrected (81 FR 51097, August 3, 2016) (‘‘AD 2016–14–01’’). AD 2016–14–01 applies to certain Airbus SAS Model A330–200 Freighter series airplanes; Model A330–200 and A330– 300 series airplanes; Model A340–200 and A340–300 series airplanes; Model A340–500 series airplanes; and Model A340–600 series airplanes. AD 2016– 14–01 requires identification of the manufacturer, part number, and serial number of the RAT, and reidentification and modification of the RAT if necessary. AD 2016–14–01 was prompted by a report indicating that, during an operational test of a RAT, the RAT did not deploy in automatic mode. AD 2016–14–01 was issued to prevent non-deployment of the RAT, which, following a total engine flame-out, or during a total loss of normal electrical power generation, could result in reduced control of the airplane. Related Service Information Under 1 CFR Part 51 Airbus SAS has issued Service Bulletins A330–29–3130 and A340–29– 4098, both dated May 3, 2017. This service information describes procedures for replacing any affected RAT hydraulic pump with a serviceable E:\FR\FM\31AUP1.SGM 31AUP1 Federal Register / Vol. 83, No. 170 / Friday, August 31, 2018 / Proposed Rules part and re-identifying the RAT module part number. These documents are distinct since they apply to different airplane models. UTC Aerospace Systems has issued Service Bulletin ERPS06M–29–22, dated March 17, 2017, and Revision 1, dated June 27, 2017. This service information identifies affected part and serial numbers for the RAT hydraulic pump. These documents are distinct since UTC Aerospace Systems Service Bulletin ERPS06M–29–22, Revision 1, dated June 27, 2017, adds a Parker part number reference to each Hamilton Sundstrand hydraulic part number. 44515 This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. relevant information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. FAA’s Determination This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all the Proposed Requirements of This NPRM This proposed AD would require accomplishing the actions specified in the service information described previously. Costs of Compliance We estimate that this proposed AD affects 103 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: daltland on DSKBBV9HB2PROD with PROPOSALS ESTIMATED COSTS Labor cost Parts cost Cost per product Up to 14 work-hours × $85 per hour = Up to $1,190 .............. $0 Up to $1,190 ........................... Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency’s authority. We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: ‘‘General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. This proposed AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division. Regulatory Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on VerDate Sep<11>2014 16:46 Aug 30, 2018 Jkt 244001 the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify this proposed regulation: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; 2. Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); 3. Will not affect intrastate aviation in Alaska; and 4. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2018-0062, dated March 20, 2018 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Airbus SAS Model A330-200 Freighter 
series airplanes, Model A330-200 and -300 series airplanes, and Model 
A340-200 and -300 series airplanes. The MCAI states:

    Four A330 RAT units were returned to the supplier due to low 
discharge pressure. These defects were detected during Airbus 
production tests. Subsequent investigations by the RAT manufacturer 
UTAS (formerly Hamilton Sundstrand) revealed that some RAT hydraulic 
pumps, [part number] P/N 5916430, were involved in an alternative 
manufacturing process of the pump pistons. This resulted in form 
deviations (rough surface finish and sharp edges), which caused 
excessive wear and damage to the bore where the pistons moved.
    This condition, if not corrected, could lead to low performance 
of the pump, possibly resulting in reduced control of the aeroplane, 
particularly if occurring following a total engine flame out, or 
during a total loss of normal electrical power generation.
    To address this potential unsafe condition, Airbus published 
[service bulletin] SB A330-29-3130 and SB A340-29-4098, providing 
instructions for identification and replacement of the affected 
parts.
    For the reasons described above, this [EASA] AD requires 
replacement of the affected parts. This [EASA] AD also requires re-
identification of the RAT module.

0764.

Other Related Rulemaking

    The FAA issued AD 2016-14-01, Amendment 39-18582 (81 FR 44983, July 
12, 2016); corrected (81 FR 51097, August 3, 2016) (``AD 2016-14-01''). 
AD 2016-14-01 applies to certain Airbus SAS Model A330-200 Freighter 
series airplanes; Model A330-200 and A330-300 series airplanes; Model 
A340-200 and A340-300 series airplanes; Model A340-500 series 
airplanes; and Model A340-600 series airplanes. AD 2016-14-01 requires 
identification of the manufacturer, part number, and serial number of 
the RAT, and re-identification and modification of the RAT if 
necessary. AD 2016-14-01 was prompted by a report indicating that, 
during an operational test of a RAT, the RAT did not deploy in 
automatic mode. AD 2016-14-01 was issued to prevent non-deployment of 
the RAT, which, following a total engine flame-out, or during a total 
loss of normal electrical power generation, could result in reduced 
control of the airplane.

part and re-identifying the RAT module part number. These documents are 
distinct since they apply to different airplane models.
    UTC Aerospace Systems has issued Service Bulletin ERPS06M-29-22, 
dated March 17, 2017, and Revision 1, dated June 27, 2017. This service 
information identifies affected part and serial numbers for the RAT 
hydraulic pump. These documents are distinct since UTC Aerospace 
Systems Service Bulletin ERPS06M-29-22, Revision 1, dated June 27, 
2017, adds a Parker part number reference to each Hamilton Sundstrand 
hydraulic part number.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

FAA's Determination

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all the relevant information and determined the unsafe 
condition described previously is likely to exist or develop on other 
products of the same type design.

Proposed Requirements of This NPRM

    This proposed AD would require accomplishing the actions specified 
in the service information described previously.

Costs of Compliance

    We estimate that this proposed AD affects 103 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
               Labor cost                   Parts cost         Cost per product         Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 14 work-hours x $85 per hour = Up              $0   Up to $1,190..............  Up to $122,570.
 to $1,190.
----------------------------------------------------------------------------------------------------------------

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII: Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701: ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.
    This proposed AD is issued in accordance with authority delegated 
by the Executive Director, Aircraft Certification Service, as 
authorized by FAA Order 8000.51C. In accordance with that order, 
issuance of ADs is normally a function of the Compliance and 
Airworthiness Division, but during this transition period, the 
Executive Director has delegated the authority to issue ADs applicable 
to transport category airplanes to the Director of the System Oversight 
Division.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would not 
have a substantial direct effect on the States, on the relationship 
between the national Government and the States, or on the distribution 
of power and responsibilities among the various levels of government.
    For the reasons discussed above, I certify this proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Airbus SAS: Docket No. FAA-2018-0764; Product Identifier 2018-NM-
074-AD.

(a) Comments Due Date

    We must receive comments by October 15, 2018.

(b) Affected ADs

    This AD affects AD 2016-14-01, Amendment 39-18582 (81 FR 44983, 
July 12, 2016); corrected (81 FR 51097, August 3, 2016) (``AD 2016-
14-01'').

(c) Applicability

    This AD applies to the airplanes identified in paragraphs 
(c)(1), (c)(2), (c)(3), (c)(4), and (c)(5) of this AD, certificated 
in any category, all manufacturer serial numbers.
    (1) Airbus SAS Model A330-223F and -243F airplanes.
    (2) Airbus SAS Model A330-201, -202, -203, -223, and -243 
airplanes.

(d) Subject

    Air Transport Association (ATA) of America Code 29, Hydraulic 
Power.

(e) Reason

    This AD was prompted by defects found during production tests of 
ram air turbine (RAT) units; investigation revealed that the defects 
were due to certain RAT hydraulic pumps having an alternative 
manufacturing process of the pump pistons. We are issuing this AD to 
prevent low performance of the pump, which, following a total engine 
flame-out, or during a total loss of normal electrical power 
generation, could result in reduced control of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.
